Whenever I attempt to select an object in Didger, another nearby object gets selected instead.

Sometimes it is difficult to select objects that are near to each other. If you click on an object to select it and another object gets selected instead, hold the CTRL key down while clicking. The CTRL key will allow you to scroll through the selection boxes until the correct object gets selected.

Alternatively, you can also select the object in the Data Attribute View (Didger 2 or 3) or the Data Manager (Didger 4 or 5).
